 * An observable store for installed agent plugins that is backed by a
 * `installed.json` file within the agent-plugins directory. This makes
 * the installed-plugin manifest discoverable by external tools (CLIs,
 * other editors, etc.) without depending on VS Code internals.
 *
 * The on-disk format stores only the plugin URI (as a string) and the
 * marketplace identifier. Plugin metadata (name, description, etc.) is
 * read from the plugin manifest on disk by the discovery layer -
 * keeping a single source of truth.
 *
 * On construction the store:
 * 1. Attempts to read `installed.json` from the agent-plugins directory.
 * 2. If no file exists, migrates data from the legacy {@link StorageService}
 *    key (`chat.plugins.installed.v1`), rebasing plugin URIs from the old
 *    cache directory to the new agent-plugins directory.
 * 3. Sets up a correlated file watcher so that external edits to
 *    `installed.json` are picked up automatically.
 *
 * Write operations update the in-memory observable synchronously and
 * schedule a debounced file write so that rapid successive mutations
 * (e.g. batch enables) are coalesced into a single I/O operation.
